Oxford Water Hardness & Quality Report (2026)

The City of Oxford, Mississippi operates a municipal water utility serving Oxford and surrounding areas in Lafayette County. Water is sourced exclusively from groundwater wells drawing from the Meridian Upper Wilcox Aquifer. The utility operates treatment facilities employing aeration and softening processes, with chlorine as the primary disinfectant. The City of Oxford Public Works Department can be contacted at 662-232-2373, and annual water quality reports are available through official reporting channels.

Oxford's water supply originates from the Meridian Upper Wilcox Aquifer, a Paleocene-Eocene geological formation. As groundwater percolates through this aquifer's mineral-rich strata, it dissolves substantial quantities of calcium and magnesium, imparting a very hard character to the raw water. The geological composition of this formation — typical of northern Mississippi's limestone-influenced bedrock — naturally produces highly mineralized groundwater characteristic of the region.

At very hard levels, Oxford's water significantly impacts household appliances and plumbing. Scale buildup accumulates rapidly in water heaters, dishwashers, and washing machines, reducing efficiency and shortening equipment lifespan. Soap and detergent effectiveness is substantially diminished, requiring higher doses for cleaning. The City of Oxford has recognized these challenges and budgeted resources to test and implement water softening techniques — including lime softening, fluidized bed reactor softening, membrane softening, and ion exchange softening. The 2023 Annual Drinking Water Quality Report confirms the system meets all Federal and State requirements with no violations and a quality score of 100/100; all detected contaminants remain within EPA Maximum Contaminant Level Goals.
